April 18, 2014

Engineering News Record (ENR) recently published an article titled “Innovative System Aids Tunnel Ceiling Slabs Removal in Boston” about the ongoing Hynes Suspended-Concrete-Ceiling Replacement Project.  Two members of the SGH team, Cory Brett and Scott DiFiore, are both quoted in the article.  Cory explains, “In the predawn hours of April 6, three flatbed trailer trucks, side by side, crept out of the Prudential Tunnel in three of the four eastbound lanes carrying a 33 ft wide, 45 ft long slab weighing 75,000 lbs–the largest of 106 sections to be removed to date.”  Scott continued on to say, “Crews installed 200 support hangers on each side of the tunnel to allow the ceiling to be cut into panels, most about 12 ft wide, 30 – 50 ft long, and weighing about 30,000 lbs.”
